BioHaven Floating Islands – easy and sustainable solutions

BioHaven floating island fully vegetated

BioHaven floating islands are a fast and cost-effective way of creating a wetland habitat or improving a water body that is unsightly or polluted. The wetlands provide an immediate and pleasing greening effect and also help to clean up the water, solving two problems at one stroke.

After just one growing season BioHaven floating wetlands leave you with attractive habitats along a river’s edges or islands in the middle of a pond or lake.

BioHaven is the only floating island system that is designed to naturalise right to the water’s edge.

Each BioHaven module is a 2 x 1 metre growing platform, interconnecting to form a wetland.

The unique modular design with internal buoyancy are easily arranged and connected together. The materials used are sustainable and recyclable.

Fast results with wetland plants establishing quickly

The modules are typically supplied with pre-established wetland plants. In just one year the increase in plant mass leads to a natural-looking river edge or island. This rapidly provides valuable habitat, which in turn leads to an increase in biodiversity like insects, birds and bats.

The root systems of the plants on the floating islands also process excess nutrients in polluted waters. This improves water quality and the wider aquatic habitat for insects and fish. BioHaven has more peer-reviewed and externally verified data than any other floating islands system when it comes to improving water quality.

Easy peasy to build BioHaven Floating Islands

BioHaven modules have an integral joining mechanism allowing for modules to be quickly and easily connected without any ancillary parts or pieces. They can be connected manually with minimal risk and installed without the need for cranes or heavy machinery.

The modules are internally buoyant throughout, not just along the edges or focused in the centre. Such stability across the whole surface area allows even narrow installations to support a fully mature vegetation scheme with diverse height and biomass distribution. A simple way to create a long riparian edge or a larger floating island.

The unique design allows the modules to be completely submerged, impacted by boats or even vandalised, without compromising the integrity of the buoyancy. The design also has multiple anchoring connection points, which can also be adjusted should the installation need to be moved elsewhere.

Sustainable solutions

BioHaven modules are made from mostly natural materials. Just over half (54%) is the biodegradable coir fibre growing medium with a further 12% of the total weight on launch made up of plant biomass, including complex pre-established root systems for water treatment.

The rest of the module consists of UV-stabilised and recyclable materials:

  • HPDE connection grid for connecting BioHaven modules (20%)
  • Thick denure HDPE growing platform (10%)
  • Marine grade closed cell foam for buoyancy (4%)

BioHaven floating wetlands are a low-cost, low-energy solution to unsightly or polluted water bodies. They are visually pleasing, natural-looking, sustainable features that also improve water quality. Contact frog environmental if you need help with a water body near you.
